To all whom twang/concern: A

Be it Vknown thatl, BENEDIKT RTTna citizen'of Switzerland, andresident of Balsthal, a small place in the Canton of Solothurn, Switzerland, have invented a Lock* ing Device for Double French Glazed lll/'in-v dows `and Doors, :of whichthe following is ya specification.`

This invention has reference to certain new and useful improvements inlocking devices particularly `adapted for use with double glazed windows and doors.` In hitherto known windows yand doors of this kind the two frames carrying the glazing of one and the same windoware' usually attached to one another by means ofscrews or the like, so that for the purpose of cleaning the inner faces of the glazings the screws had to be detached to ,render the said glazings accessible. `This naturally involved considerable time and labor. f

It is the object of the present invention to obviate these drawbacks, a locking device,`

hereinafter described, beingprovided which allows of the locking andwopening respectively of the two adjacent frames of double glazed windows. i The accompanying drawing shows the application of the locking device on a French window.

. In this drawing: Figure 1 shows a front `elevation of the complete mechanism; Fig.

2 shows a side elevation thereof; Fig. 3 shows a section through line 'Ar-B, Fig. 1;

,Fig l shows a vertical Vsection through line C-D of Fig. 5, the ltwo framesjof the common window being in 'disengaged position,` l a detail also beingillustratedin section;`

Fig. 5 shows a view similar to that illus" trated in Fig. 1. l l

a and b designate the two windows, each window comprising two frames 1 and 2 and 3 and 4 respectively, and each of the frames having a glazing `mounted therein in the usual manner. The frame 1 has a groove within which a vertical rod 5 is adapted to slide,`the lower' end ofthe said rodengaging,

when the corresponding window is closed, in

a sleeve or abridge of known construction provided and arranged below the lower` end of the windows, thereby keeping the two windows closed. Pivoted to the frame 1 at the point designated by 6is `a U-shaped handle 7 vboth ends thereof being fashioned into specification bf Letters Patent. v

`plates S. One of these plates'S is adapted to engage, when the windows are closed, with a hook 9 mounted on the frame 3 ofthe win-` dow Z), and the otherplate lies partially in a recessprovided in the rabbethledge oit' the i frame i... .This latter plate is connected with thelvertical rod by means of an arm 10 integral ywiththis rod, the said arm 10 being devised so that it can play in a suitable opening provided in the frame 1.

Theobjectof the handle 7 is to permit or' the vertical movement of the rod 5 which,

yat acer-tain distance-from each other, has

two integral projectionsll (Fig. 4) each of thev latter moreover being provided with a transversely disposed `head 12. Provision is made immediately opposite the said pro-- jections 11 of plates 13 mounted in suitable recesses ofthe frame 2, these plates having longitudinal slots 14 terminating in square openings l5. kThe latter allows of the disengagement of the corresponding projections 11 with head 12 from the recesses in the frame 2 when the two frames are to be disconnected. On the other hand ii these frames are to be` attached to one another the vrod 5, subsequent to the insertion of the projections 11 into the square openings `15, is moved upward so that the heads 12 of the projections l1 engage within the slot 14 of j the plates 13.

When the windows are closed thehandle 7 is in the position according to Fig. l, and the projections l1, 12 `are engaging within the openings 15 of the plates 13. Assuming that the handle 7 is nowturned upwardly,

therod is also moved in an upwardy direc-r tion, its lower end thereby being withdrawn from the locking sleeve or bridge and allowingofthe opening of the window a. Simul taneously with the movementfof the handle 7 the projections 11 are moved behind the narrow slot la of the plates '13 so that the frames 1 and 2 are still fastened to each other. Then the opening of the window a has taken place the handle 7 may be moved into the position shown in full lines in Fig.` 5 thus causing a downward movement of the rod 5 and bringing the projectionsll j opposite the openings 15. VIn this position projections ll` maybe disengaged, that is the frame 2 may be swung outward thereby allowing an easy access to the glazings of vboth frames.

- be detached fromeach other, provision is made Within vthe frame 4 of the Window I) of a vertical groove Within which a rod 20 is'adapted to slide (Figs. 2 and 3). At a suitable distance from each other are tvvo hooks 2l integral with the said rod 20- which` normally, `that is in closed position. of thc.

trames, project intoa recess in the frame 4- and engage with plates 22 bridging saidi` bolt25 the latter being journaled in a plate 26 mounted on the frame Vhen the Window Z) is disengaged from window a, the aforesaid adjusting lever 9A isadapted to be swung from its vertical position, Figlinto a horizontal position, thereby moving the .rod 20 in a downward direction `and causing the hooks 21 to lie below the plates 22. In this position the frames -3 and /1 mayv easily be detached from each other and in this also, the glazings ofboth frames are accessible.

I-Iaving now fully described 4my said in- Copie's of this patent may be obtained for vention what I claim anddesire to secure by Letters Patentjis-L-v K d l y In a lockingr device for 'double glazed French Windows, the combination of a pail" f 1 of frames and a frame-adapted to engage therewith, a U-shaped. handlepivoted to one of the `frames,'said handle having'a plate apertured to receive a pin, the said plate bc-` ing movable Withthe handle, a. rod having a pin entering the slot of the plate, members on the rod adapted to interlockfwith the other frame of the pair, aA-pla'te-on the frame Withvvhich the'rst Vmentioned pairv of frames coacts,van engaging device on the said lastl mentioned plate, anda member on the U-shaped handle adaptedfto interlock with the engaging device.
